I dont know what happened to the card, the dealer said bought it without it.
But that is not possible that the car can just work with the original card and not with a new one. Or you can reprogram the new card to the car and thr navigation system, if thar is not possible that will be my last lexus. No Bmw or mercedes i had had such a problem with the navigation system. I am sad about that. I will wait for the next and see what happened if my dealer has the new unit at the shop. But there can ve the next problem, the german law says that the dealer where i bought it has to fix my car but he don't have to use new parts, and if the navigation unit or the card cannot be reprogrammed, so in this way the car never can be used again without using a new unit woth new sd card.
Oh 900 dollars is a lot, but lexus likes to steal the money from us here in germany, if you are not a Millionair you cant do a big service with changing all brake pads and discs, i had a example for my old gs 450h here at the official lexus station about 2000 euro. So i do the service at lexus but parts and everything i go to a free mechanic becauae dont want to give all my money to lexus.
